Emhlabeni wokuxhumana, amaswishi asebenza njengomgogodla, ahambisa kahle amaphakethe edatha ezindaweni zawo ezihlosiwe. Ukuqonda izinto eziyisisekelo zokusebenza kokushintsha kubalulekile ukuze ubambe inkimbinkimbi yezakhiwo zenethiwekhi zesimanje.
Empeleni, ukushintsha kusebenza njengedivayisi ye-multiport esebenza kusendlalelo sesixhumanisi sedatha semodeli ye-OSI. Ngokungafani namahabhu, asakaza idatha ngokungakhethi kuwo wonke amadivayisi axhunyiwe, amaswishi angadlulisela ngobuhlakani idatha kuphela kudivayisi ethile lapho aya khona, athuthukise ukusebenza kahle kwenethiwekhi nokuphepha.
Ukusebenza kweswishi kuncike ezingxenyeni eziningi ezibalulekile nezinqubo:
Ukufunda ikheli le-MAC:
Iswishi igcina ithebula lekheli le-MAC elihlobanisa amakheli e-MAC nezimbobo ezihambisanayo eziwafundayo. Uma uhlaka lwedatha lufika embobeni yokushintsha, iswishi ihlola ikheli lomthombo we-MAC futhi ibuyekeze ithebula layo ngokufanele. Le nqubo ivumela ukushintshwa ukuthi kwenze izinqumo ezinolwazi mayelana nokuthi izodlulisela kuphi izinhlaka ezilandelayo.
Phambili:
Uma iswishi ifunda ikheli le-MAC ledivayisi exhunywe embobeni yayo, ingadlulisela ozimele kahle. Lapho uhlaka lufika, iswishi ithintana nethebula lekheli layo le-MAC ukuze inqume imbobo ephumayo efanele yekheli le-MAC okuyiwa kulo. Uhlaka lube seludluliselwa kuleyo mbobo kuphela, kunciphisa ithrafikhi engadingekile kunethiwekhi.
Ukusakaza kanye nezikhukhula ze-unicast ezingaziwa:
Uma iswishi ithola uhlaka olunekheli le-MAC okuyiwa kulo elingatholakali kuthebula lekheli layo le-MAC, noma uma ifremu iqondiswe ekhelini lokusakaza, iswishi isebenzisa ukukhukhula. Idlulisela phambili ozimele kuzo zonke izimbobo ngaphandle kwembobo lapho uhlaka lutholwa khona, iqinisekisa ukuthi uhlaka lufinyelela lapho luyiwa khona.
I-Address Resolution Protocol (ARP):
Ukushintsha kudlala indima ebalulekile ekusizeni inqubo ye-ARP ngaphakathi kwenethiwekhi. Uma idivayisi idinga ukucacisa ikheli le-MAC elihambisana nekheli le-IP elithile, isakaza isicelo se-ARP. Iswishi idlulisela isicelo kuzo zonke izimbobo ngaphandle kwembobo okutholwe kuyo isicelo, okuvumela idivayisi enekheli le-IP eliceliwe ukuthi iphendule ngokuqondile.
Ama-VLAN neziqu:
Ama-LAN abonakalayo (ama-VLAN) avumela ukushintsha ukuhlukanisa inethiwekhi ezizindeni ezihlukene zokusakaza, ukuthuthukisa ukusebenza nokuphepha. I-Trunking inika amandla iswishi ukuthi ithwale ithrafikhi isuka kuma-VLAN amaningi ngesixhumanisi esisodwa esibonakalayo, okwandisa ukuguquguquka ekwakhiweni kwenethiwekhi nokucushwa.
Kafushane, amaswishi akha isisekelo sengqalasizinda yenethiwekhi yesimanje, esiza ukuxhumana okusebenzayo nokuvikelekile phakathi kwamadivayisi. Ngokuhlolisisa ubunkimbinkimbi bokusebenza kokushintsha, abalawuli benethiwekhi bangathuthukisa ukusebenza, bathuthukise ukuvikeleka, futhi baqinisekise ukugeleza kwedatha okungenazihibe kunethiwekhi yonkana.
I-Toda igxile ekukhiqizeni amaswishi nokwenza ngokwezifiso ukwakhiwa kwenethiwekhi kumabhizinisi.
